To all whom it may concern.-

Be it known that I, KARL GIESE, a subject of the Emperor of Germany,residing at Offenbach-on-the-Main, in the German Empire, have inventedcertain new and useful Improvements in Sewing-Machines for Making StrawBottle-Covers, (the same having been patented to me in Great Britainunder Patents No. 2,130, dated April 27, 1883, and No. 4,925, datedApril 8, 1886; in Germany under Patents No. 24,617, dated November 10,1883, and No. 35,872, dated December 23, 1885; in Austria-Hungary underPatents No. 11,584 and No. 38,924, dated September 17, 1886, and inFrance under Patent No. 173,691, dated May 3, 1886;) and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will onable others skilled in the art to which itappertains to make and use the same.

This invention relates to machines for manufacturing straw wrappers forbottles.

The object of the present invention is to provide a machine forautomatically producing straw wrappers for bottles of every description.The straw of which the wrapper are made, is first laid on the tray ofthe machine, which isthen transported under a cylinder containinga partof the sewing devices, said cylinder having a variable diameter whichmay be adjusted to the size of the wrapper being made. The straw formingthe wrapper is held on the cylinder while being sewed, and graduallydrawn around the same by hand until finished, when by a movement of themachine frame, the removal of the finished wrapper from the cylinder isaccomplished. The formation of the stitches is effected by needlesmounted on rods vertically movable in the machine frame, while the traycarrying the straw is continuously moved for ward step by step by meansof an eccentric and ratchet gear.

In order to make my invention more clear,

I refer to the accompanying drawings, in which similar letters denotesimilar parts throughout the several views.

Referring to Figs. 1, 2, 3 and 4, the tray a,"

on which the straw is laid, is supported on two guides 17, b, pivoted tothe machine frame 6, e, by means of the lugs 0,0, on shaft d, ar-

battens the straw to be sewed is evenly spread out. The weight of thestraw is sufficient to compress the springs a, so that the points of thespikes pass in to the straw layer holding the same in position (Figs. 4,5 and 6). After the straw has been spread out on the battens a, ad, thecover 12 is closed and fastened down by the catch b (Fig. 1,) the tray ais transported along the guides 11, b, in the following manner:The cog dloosely mounted on the shaft d engages in the rack a and is providedwith lateral circle of teeth (1 in which a ratchet d mounted on lever (iengages. The cog d is intermittently rotated from the main,.drivingshaft 6 of the machine, by means of the eccentric d rod d and pin (1 andlever (i pivotally supported at its end by shaft d. The ratchet (1(,Figs. 3 and 5) is pivoted to the lever 11 at d and actuated away fromthe teeth (1 by spring d In order to set the ratchet d in operation thehandlef (Fig. 3) must be brought into the position shown in dottedlines, whereby the. ratchet is forced on to the teeth against thepressure of its spring (W by means of intermediate lever and rod f f Theratchet is retained in this position, by means of the nose f on redfgripping under the lever J". This whole device is attached to theguides 19 [2 (Figs. 3, 15'and 16). As soon as the tray begins to moveforward, the needles must be brought into operation, which isaccomplished by the herein-after described mechanism.

When the machine is set in motion by means of the treadle 6 the verticalrod g moves up and down several strokes without taking the needles withit. As soon, however, as the roll 7& mounted in a lever arm at the upperend of the rod it comes against the glide bar a which is attachedunderneath the tray, and moves with it, the lever arm and roll will beturned from the position shown in dotted lines to that drawn in full, inFig. 16. Thus the rod his turned about a quarter of a revolution, as thelever arm. is rigidly attached thereto, whereby the rod g is coupledcausing the vertical motion of the needle rods in the following manner:The rod h is attached to the vertically movable frame 7; at t" and 2'and at its lower part is turned eccentrically at h. This eccentric hlies in a slot is in the slide plate (Fig. 19) which slides in a casing70' on plate It. This slide plate 70* has a central slot is for thereceptionv of the rod g, while to the plate It are attached the needlerods Z, l. As soon as the rod It has been turned by means of the roll72. being operated as hereinbefore described, by the glide bar a of theadvancing tray, the slide plate k is pushed back as shown in Fig. 20 indotted lines. Underneath the slide-plate 70 and attached to the same, isa wedge 70 which, when the slide moves backward, is removed from betweenthe shanks of the gripper it 70*, causing the same to close into theslits g of the rod 9 under the influence of springs 70, k arranged onrods 70 k pivoted to the slide at 70 The plate 70 as also theneedle-rods Z, Z are now coupled to the rod 9 and move vertically up anddown with the same. As soon as the needle-rods which are guided in thecross pieces 1, t, of the frame '5, have passed up and down three timesand the tray a has advanced a corresponding distance, the projection aof the tray 61., (Figs. 6 and 9) strikes the nose at of the lever npressing the same downward into the position shown in dotted lines inFig. 9. This lever nis pivoted at a and moves in cavity 0 in the endplate 0 of the cylinder 0 (Figs. 7, 8 and 9). The lever n actuates asecond lever 19 which is rigidly attached to the rod 10. To the rod 1)are attached, inside the cylinder, the arms 19', 13 which, by thepartial revolution of the rod 19 are pressed against the shanks r 7", ofthe nippers r, W, hereinafter described, opening the same in theposition shown in dotted lines in Figs. 7 and 10, letting go the ends oftwo threads previously clamped therein by hand, which must be done atthe beginning of each wrapper. The ends, however, are only let looseafter the needles have made the first three stitches; otherwise thethread would get loosened and the straw would be badly attached.

The arrangement of that part of the sewing mechanism which is in thecylinder is as fo1lows:--Arranged on each side of the cylinder 0 aretwolongitudinally sliding rodsrand g which project at one end throughthe eylinder and recesses in the side e of the frame. The ends arepivotally connected to the levers r and The rods r and q are guidedinside the cylinder, in recesses 0 in the crosspieces 0 Underneath therod q are attached two transversely projecting thread carriers q, 1while to rod 0", the cheeks r, r of the thread nippers are screwed. Themovable cheeks and shanks r T of the nippers are held close on to thecheeks 1", W, by springs arranged in the casings 0' which press againstpins 7*, 0"", of the movable shanks. the bearings of the rods 19 0 thesupport blocks to which the transverse pieces 0 are screwed. 0 0 are theorifices for the needles which are bored through bosses cast on to thecylinder. The upper part 0' of the cylinder is hinged to the lower partand opens as shown in dotted lines in Fig. 11. The whole cylinder isopen at the right end, while the end plate 0 of the left end is attachedby means of screws to the side 6 of the machine frame. The rod (1 ismoved longitudinally backward and forward in the cylinder from therocking-lever pivotally attached at g to the projection of the frame,(Fig. 1.) The ends of the threads having been let loose by the grippersas hereinbefore described,and drawn out of the cylinder by the advancingtray, the said thread passes from the wrapper through the needleorifices 0, through the guide holes 0 in the right hand side of thebridge 0 then through the eyes of the spring bolts 0 and back throughthe left hand holes 0 of the IIO 0 0 are '13 in dotted lines).

bridge 0 through various tightening devices hereinafter described, tothe bobbins mounted on the bracket e in the lower part of the machineframe 6 (Figs. 1 and 2). The front one of the two bridges 0 is providedwith three holes, one of which. serves to conduct the second threadwhich passes to the second bridge (Figs. 7 and 8). When the rod qisin aposition of rest the thread carriers g 9 lie behind the needle orifices0* (Figs. 7, 14, and lVhen the rod qis drawn out, by means of the leverg the carriers g, g catch up the thread and draw it over the needleorifice o in the manner shown in Figs. 12 and 13, so that the needles onentering the slits or orifices 0 will catch the threads and draw themdownward into the straw. The needles'draw the threads through the strawas shown in Fig. 18, thus forming chain stitches, as soon as the needleshave descended, the rod and carriers q, (1 are slid back by lever (1This latter lever is actuated by the arm havinga curved slit Z whichrises and falls with the frame 2, being attached to the needle rod b.

After the wrapper has been sewed in the manner shown in Figs. 5 and 6,and the ends of the thread secured against raveling out, by allowing themachine to make several stitches more than actually necessary, the guidebars b, b with the straw tray aare now tipped into the position shown indotted lines in Fig. 4, to enable the more convenient removal of thewrapper from the cylinder. The tipping of the tray is accomplished byturning therhandle s mounted on the side I) of the frame (Fig. 1), andthus withdrawing the spring bolts 8'. from the lever s which is pivotedat The other end of the lever s is pivoted to the upright .9 which isrigidly at tached to the guide. rail or rod 17. By liberating the levers from underneath the spring catch '8', the guide-rails b, band strawtray may be inclined downward until the said lever s strikes orrests onthe upper corner of the side e-of the frame. A slotted flat piece b ismovably attached to the guide bar b in the slot of which passes thearma" of the angle lever r pivoted to the frame e at r (Figs. 2, 4 and 8).The lever r operates the rod 1" to which the grippers 1", r are attachedin the cylinder 0. On tipping the guide bars I), b and tray 0., themotion is transferred to the lever T which drives the rod r into thecylinder, causing the grippers r, r to open, owing to their shanks W, Tcoming against the spring stops t, t, arranged on the blocks 0 in thecylinder.

In the moment while the grippers are open, they grip the thread as shownin Fig. 14, and hold it fast, as they close again as soon as the shankhas passed the spring stop t, under influence of their springs T Inclosing, they cut off the threads and the straw wrapper may be easilyremoved vfrom the cylinder.

On returning the guide rods 1), b and tray a to their horizontalposition where they are secured by catch 5, the lever r draws the rod 4"back out of the cylinder, on which movement the shanks W, T pass thestop if, pushing or turning them against the pressure of their springs,flat onto the cylinder wall as they have no support or stop 25' on thisside. The sufficient quantity of straw only, for the particular size ofwrapper being made, should be laid on the battens a, 0. of the strawtray (Figs. 3,4, 5, 6, and 8) so that the vertical motion of the needlesb b and the forward movement of the tray (1. by means of its cog 61,need only be continued long enou h to sew the straw, and when this iscompleted, the needles Z Z and wheel 01 are disengaged so thattheneedles no longer rise andde scend and the tray stops automaticallyin. spite of the fact that the treadle e crank c and driving shaft 6continue to run. The mechanism for efiecting the automatic disengagementof the devices mentioned, operates as follows: On the longitudinal-stripa of the frame a is arranged an angle iron a l, having a slit 0, and aguiding surface 0. in. which it carries a sliding plate at, having anarm 0. bent round at right angles to it. The roll h of the vertical rodIt runs on this rail a, on the guide surface 01, (Figs. 15 and 16)until, owing to the advance of the tray a, the roll. reaches the cornera, of the sliding .plate a, where it runs off. The running off. ofitheroll it causes therod h to turn in its bear-.- ings in thefollowingmannerpAn .arm h is arranged on the lower end of the rod h, as. shown in.Figs. 1, 4, 21, and 22, in which arm is mounted a pivot h. which isencircled by a spring 'm, passes through the pivot 77. As soon now,asthe roll hi, runs oflf its supporting slide a, the spring m pressesagainst arm k and turns the rod hto a certain extent, whereby theexcentric part h ofthe rod h pulls the slide plate 10 forward, pressingthe wedge 10 against the projections it, of the grippers k3, and openingthesame, thus withdrawing their cheeks from the notches g and freeingthe rod g as shown in Fig. 19, in dotted lines. In order to "prevent thegripper k from opening while the plate It and the whole locking deviceare in a raised or partially raised position, whereby the same wouldfall down and damage the mechanism,the.following device is provided; Theautomatic disengaging mechanism cannot operate until the set screw 10 ofthe plate One end of the rod m,

It strikes the thumb m which it presses downling until the-lock is atits lowest position.

When the needle rods are coupled, theset screw 10 will, it is true,depress the lever m at every stroke, butthis does. not affect theworking as its end simply falls back behind the catch of the arm itagain, on the ascent of the needle rods 1', the rod h not being able toturn until the roll 7L2 has run off its guide surface a.

The rail 0}, of the angle iron a besides actuating the disengagingdevice, also serves to set the pawl d out of gearing with theratchet-crown (Z of the driving wheel d in the following manner: The arma projecting at right angles to the rail (L projects over the lever f Asthe tray a and with it the rail a, advances, the transverse arm astrikes the projections f, of the lever f thus on advancing furtherdepressing lever f and elevating the end of the same, which had hithertoretained the rod f with its projection f. The lever f is thus freed(Fig. 15) and springs into the position shown in Figs. 1 and 3 undertheinfluence of its springf Thus, the rod f by means of the intermediateconnections f, f is retracted from the pawl d allowing the flat spring dto operate freely, when it detracts the pawl d from the ratchettoothing. The tray a is now stationary, even when the lever a which ispivoted to the shaft on both sides of the wheel d for the sake ofgreater stability, continues to oscillate, thus obviating the necessityof a loose pulley in the driving gear. The tray or may be pulled backinto the position shown in Fig. 3, by means of the handle a I11 order tomake wrappers of a larger diameter, an extra piece 1) is attached to thecylinder, as shown in Fig. 17. The prolonged operation of the sewingmechanism as also a later disengaging of the various devices isaccomplished in the following manner. The rail a is slid farther alongin its slit a and guiding surface (L13, thus necessitating the roll h todescribe a longer way, before it reaches the end a and the arm 0, willdepress the lever f later. The quantity of straw laid on the tray a alsovaries with the size of the wrapper to be made. The two threads comingfrom the bobbins w, w, are held tight, by being taken first through theguide holes of the holder 00, then to the clamp disks :0, round therollers :0 through the guide 00 under the guard 00, and finally backthrough the guide at, through openings in the frame at the end of thecylinder 0, and then further in the manner as hereinbefore described.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a machine for making straw wrappers,
